Seems to a different behaviour when doing a fork+pthreads_create... somehow. 
Try to remove the fork and the setgid from posix/init.c:my_daemon and compile 
it again (against uclib of course). You should notice that it works without 
any problems.
If you do a static build against a current glibc on i386 (2.7 here) it works 
as expected.
So I would guess a uClibc specific behaviour when calling pthread_create after 
a fork. The thread (unix_listen) itself runs without any problems but the main 
thread seems to be blocked at
 pthread_create( &unix_if.listen_thread_id, NULL, &unix_listen, NULL );
in posix/init.c:apply_init_args.

Please read http://www.mail-archive.com/uclibc@uclibc.org/msg00357.html for 
some hints.

Best regards,
